NAME

       XmScrollBar — The ScrollBar widget class "XmScrollBar" "widget class" "ScrollBar"

SYNOPSIS

       #include <Xm/ScrollBar.h>

DESCRIPTION

       The ScrollBar widget allows the user to view data that is too large to be displayed all at
       once. ScrollBars are usually located inside a ScrolledWindow and adjacent  to  the  widget
       that  contains the data to be viewed. When the user interacts with the ScrollBar, the data
       within the other widget scrolls.

       A ScrollBar consists of two arrows placed at each end of a  rectangle.  The  rectangle  is
       called  the  scroll  region.  A smaller rectangle, called the slider, is placed within the
       scroll region. The data is scrolled by clicking either  arrow,  selecting  on  the  scroll
       region,  or  dragging the slider.  When an arrow is selected, the slider within the scroll
       region is moved in the direction of the arrow by an amount supplied by the application. If
       the mouse button is held down, the slider continues to move at a constant rate.

       The  ratio  of  the  slider  size  to  the scroll region size typically corresponds to the
       relationship between the size of the visible data and the total  size  of  the  data.  For
       example, if 10 percent of the data is visible, the slider typically occupies 10 percent of
       the scroll region. This provides the user with a visual clue to the size of the  invisible
       data.

       If  the  ScrollBar  parent  is  an automatic ScrolledWindow, the XmNtraversalOn default is
       True. Otherwise, the default is False.

       ScrollBar holds the XmQTnavigator traits.

   Classes
       ScrollBar inherits behavior, resources, and traits from the Core and XmPrimitive classes.

       The class pointer is xmScrollBarWidgetClass.

       The class name is XmScrollBar.

   New Resources
       The following table defines a set of widget resources used by the  programmer  to  specify
       data.  The  programmer  can  also set the resource values for the inherited classes to set
       attributes for this widget. To reference a resource by name or by class  in  a  .Xdefaults
       file,  remove  the  XmN or XmC prefix and use the remaining letters. To specify one of the
       defined values for a resource in a .Xdefaults file, remove  the  Xm  prefix  and  use  the
       remaining  letters  (in either lowercase or uppercase, but include any underscores between
       words).  The codes in the access column indicate if the  given  resource  can  be  set  at
       creation time (C), set by using XtSetValues (S), retrieved by using XtGetValues (G), or is
       not applicable (N/A).
